Is global warming caused by humans? Is Barack Obama a Christian? Is evolution a well-supported theory?
You might think these questions have been incontrovertibly answered in the affirmative, proven by settled facts. But for a lot of Americans, they haven't. Among Republicans, belief in anthropogenic global warming declined from 52 percent to 42 percent between 2003 and 2008. Just days before the election, nearly aquarter of respondents in one Texas poll were convinced that Obama is a Muslim. And the proportion of Americans who believe God did not guide evolution? It's 14 percent today, a two-point decline since the '90s, according to Gallup.
What's going on? Normally, we expect society to progress, amassing deeper scientific understanding and basic facts every year. Knowledge only increases, right?
Robert Proctor doesn't think so. A historian of science at Stanford, Proctor points out that when it comes to many contentious subjects, our usual relationship to information is reversed: Ignorance increases.
He has developed a word inspired by this trend: agnotology. Derived from the Greek root agnosis, it is "the study of culturally constructed ignorance."
